I think [Winston] Churchill said it was " [democracy] the worst of all systems except for all the others." And that's probably true. It's never gone easily.

When I came into office, people said, 'Billionaire? How do they live? What do they eat? How do they sleep?' Today, they see me on the subway coming uptown. A couple of people say hi, some people smile and nod. Some people just sleep. It's not an issue.

If you don't encounter setbacks in your career, if you don't have doubts and disappointments , let me tell you, you're not dreaming big enough.

I think that ... none of [the candidates in he third party] have the courage to do what's right for the country. And I have, now, two grandchildren, which I didn't have before. I'd like to leave them a better world.

Keep in mind, Mike Bloomberg's kids and grandkids are breathing that air just like the coalminers' families are breathing that air. And the coalminers are the ones that have the conflict. They want their jobs, I understand that. They need to be able to feed their families. They also have to worry about their health and the health of their families.

Progress is not inevitable. It's up to us to create it.

I like the theater, dining and chasing women. Let me put it this way: I am a single, straight billionaire in Manhattan. It's like a wet dream.
